Final answer:
Gerry Low-Sabado's traditional ceremony before archaeological digs was based on indigenous practices of honoring ancestors, similar to those of Sagada people and Maya that create a vital link between the living and their ancestors.
Step-by-step explanation:
Gerry Low-Sabado's traditional ceremony before archaeological excavations is an embodiment of practices deeply rooted in the respect for ancestors and ancestral customs. This form of ritual, which is an intrinsic part of many indigenous cultures' heritage, honors the deceased and establishes a connection with the past. For instance, in various cultures, such as the Indigenous people of Sagada and the Maya, ancestor veneration is central to their spiritual practices. The Maya, in particular, believed deceased family members served as a bridge between heaven and earth, creating family shrines for ritual practices connected to their complex calendars. Similarly, practices like the Navajo's commemoration of the Ancestral Puebloans and the Kayapo re-affirmation ceremony all resonate with the concept of venerating ancestors. The focus on ancestor worship, as seen through ceremonies and burials, is often intertwined with seasonal changes and astronomical observations, underlining the profound connection between the living, their predecessors, and the cosmos.
